Nonlocal Transport in Cr-doped (Bi,Sb)2Te3: Absence of Nonchiral Edge States
Valery Ortiz Jimenez, Paul M. Haney, Farzad Mahfouzi +3
The quantum anomalous Hall effect shows great promise for realization of the ohm without the need for an external magnetic field. The most mature material platform is magnetically…
A unified realization of electrical quantities from the quantum International System of Units
Linsey K. Rodenbach, Jason M. Underwood, Ngoc Thanh Mai Tran +12
In the revised International System of Units (SI), the ohm and the volt are realized from the von Klitzing constant and the Josephson constant, and a practical realization of the a…
From Wye-Delta to Cross-Square Recursion Configurations in Graphene-Based Quantum Hall Arrays
Ngoc Thanh Mai Tran, Marta Musso, Dominick S. Scaletta +8
In electrical metrology, the quantum Hall effect is accessed at the Landau level filling factor ν = 2 plateau to define and disseminate the unit of electrical resistance (ohm). Th…
Influences of the Minkowski-Bouligand Dimension on Graphene-Based Quantum Hall Array Designs
Dominick S. Scaletta, Ngoc Thanh Mai Tran, Marta Musso +7
This work elaborates on how one may develop high-resistance quantized Hall array resistance standards (QHARS) by using star-mesh transformations for element count minimization. Ref…
Implementing Pseudofractal Designs in Graphene-Based Quantum Hall Arrays using Minkowski-Bouligand Algorithms
Dominick S. Scaletta, Ngoc Thanh Mai Tran, Marta Musso +5
This work introduces a pseudofractal analysis for optimizing high-resistance graphene-based quantized Hall array resistance standards (QHARS). The development of resistance standar…
